The report is provided on an annual basis and follows the Updating and Screening Assessment (USA) and Detailed Assessments carried out in 2003 and 2004 respectively, as part of the second round of Review and Assessment. The schedule for future reporting has been reproduced in Appendix 1. The objective of the Progress Report is to provide continuity in the Local Air Quality Management (LAQM) process, by identifying any potential changes in air quality that might occur between the scheduled Review and Assessments that are undertaken on a three-yearly basis. They are intended also to help local authorities by providing a means for communicating air quality information, increasing the effectiveness of the monitoring effort being carried out and providing a cost effective solution to address future monitoring needs. This Progress Report has been compiled with reference to the Progress Report Guidance (LAQM.PRG (03)), published by Defra in 2003. It presents information that has been collated since the production of the USA report, including air quality monitoring data, information about emission sources and any proposed developments that have the potential to affect air quality in the District. 1.2 Previous assessments of air quality Epping Forest District Council carried out the first round of the Review and Assessment of air quality, including Stage 1, 2 and 3 reports, between 1998 and 2000. The first round assessments (Stages 1, 2 and 3) concluded that it was not necessary to declare any Air Quality Management Areas (AQMAs) for any pollutant. The USA reconsidered the seven health based air quality objectives and was completed in September 2003. The USA concluded that a detailed assessment was required for nitrogen dioxide (NO2) due to road traffic emissions from the M25 (West of the M11), High Street (Epping), Hainault Road (Chigwell), Church Hill (Loughton) and A121 Link Road (Waltham Abbey). The Detailed Assessment considered the annual mean objective for NO2 utilising the ADMS- Roads dispersion model. The results of the modelling exercise indicated that NO2 concentrations at receptor locations would not exceed the annual mean objective value (40 µg/ m3), with the possible exception of residential receptors in the immediate vicinity of the A121 Link Road/ A112 Junction (Waltham Abbey) and the Hainault Road/Manor Road junction (Chigwell). It was recommended in the Detailed Assessment that NO2 monitoring should be undertaken at these and other locations to verify the modelling results. Reference was also made to undertaking further monitoring at the A121 Church Hill/ A1168 Rectory Lane Junction. An addendum report to the Detailed Assessment has subsequently been commissioned to further examine NO2 concentrations at these receptor sites using additional monitoring data.

The results of the further NO2 monitoring (focusing on receptors) are shown in Table 1.3.1, where the measured concentrations are shown with the ADMS modelled results from the Detailed Assessment. Table 1.3.1 – Comparison of modelled and measured results Location Average modelled Average measured kerbside NO2 receptor NO2 concentration (µg/m-3) concentration (µg/m-3) A121 Link Road/A112 45.4 31.5 junction (Waltham Abbey) Hainault Road/Manor 40.8 32.8 Road junction (Chigwell) Church Hill (Loughton) 42.9 31.4 The 2004 monitoring results confirm that it is not necessary to declare an AQMA within the three Assessment Areas, and that the Detailed Assessment 2003 verified results were overly precautionary in these locations. The addendum report recommends that monitoring be continued at the existing receptor locations to demonstrate compliance with the Objective, and it is the Councils intention to do this for as long as permission is retained to maintain the diffusion tubes at these locations by the owners of the properties. The addendum report further recommends that consideration be made to an additional receptor location along the A121 Link Road and at (105) Manor Road to confirm the projected drop-off in NO2 concentrations from the kerb from the kerbside sites with highest concentrations (No. 12 & 30), These will be deployed as occupier permissions allow. The full Detailed Assessment addendum report is attached to this Progress Report as Appendix 2. 2.0 Emissions update 2.1 Industrial emissions sources During the Updating and Screening Assessment in 2003, it was noted that there was only one Part A industrial source within the district (Phosphor Technology Ltd.), and this process has now ceased to operate. It was also noted in the USA, that there were 21 Part A processes in the neighbouring authorities which were within 5 km of the boundary of the district, although it was concluded that the Part A processes were not expected to have a significant impact on local air quality for receptors within the District. At the time of the USA, there were and 15 Part B industrial sources and 17 petrol stations in the District. These processes are listed in Table 2.1.1. Page 3 of 17 LAQM Progress Report, 2005. Since the USA, 2 of the industrial sources (Nazeing Glassworks and Lancaster Bodycentre) are no longer authorised, and four waste oil burners have commenced operation (Automatt, Keithan Motor Services, Eppingdene Automotive and Wyn Thomas Servicing). Of the 17 petrol stations, 2 have ceased to operate (Total Convenience Store and Esso Wintry Park), whilst two others have increased the volume of their turnover (Neales Garage and Warrenwood Service Station). Two others have been listed also, although they have a low volume turnover. The changes to the processes are summarised in Table 2.1.1.
